Finding superconductivity in nickelates

The study of superconductivity is littered with disappointments, dead ends, and serendipitous discoveries, according to Antia Botana, professor of physics at Arizona State University.

Simulating matter on the nanoscale with AI

In a paper published today in the scientific journal Science, DeepMind demonstrates how neural networks can be used to describe electron interactions in chemical systems more accurately than existing methods.

Hammer-on technique for atomic vibrations in a crystal

Vibrations of atoms in a crystal of the semiconductor gallium arsenide (GaAs) are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial distribution of charge ...

Laser takes pictures of electrons in crystals

Microscopes of visible light allow scientists to see tiny objects such living cells. Yet, they cannot discern how electrons are distributed among atoms in solids. Now, researchers with Prof. Eleftherios Goulielmakis of the ...
